La conservation du patrimoine urbain, catalyseur du renouvellement des pratiques urbanistiques? : une réflexion théorique sur l'appropriation de la notion de patrimoine urbain par l'urbanisme

Cette thèse questionne l’apport de la conservation du patrimoine urbain à l’urbanisme. Il y est avancé que l’association entre la conservation du patrimoine urbain et l'urbanisme, dans leur cadre conceptuel actuel, plutôt que d’être le catalyseur du renouvellement de l’urbanisme, a perpétué une appréhension fragmentée et une atomisation de l'établissement, consacrant ainsi le paradigme fonctionnaliste, qui conditionne encore largement les pratiques urbanistiques contemporaines, au Québec notamment. En effet, bien que depuis les années 1960 la conservation du patrimoine soit présentée comme le fil rouge dans le redéploiement de la compétence d’édifier, plusieurs études soulignent les résultats mitigés de nombreuses expériences de conservation ainsi qu’une contribution limitée relativement à la formulation des projets urbains. Plus particulièrement, malgré la reconnaissance de l’intérêt de la patrimonialisation et de la fécondité potentielle de l’idée de patrimoine en général, l’urbanisme n’est pas parvenu à en définir les termes de la contribution, tant au plan conceptuel que processuel, en regard de sa propre projectualité. De ce fait, il ne réussit pas à affranchir la réflexion patrimoniale du registre de la conservation afin de se l’approprier véritablement. Cette thèse explique les causes de cette incapacité à partir d’une analyse des conditions de l’appropriation de la notion de patrimoine urbain mises de l’avant par l’approche giovannonienne. Celle-ci, fondamentalement urbanistique, propose une conception du patrimoine urbain qui s’émancipe du monument historique et du registre de la conservation. Indissociable d’une projectualité urbanistique, l’intérêt pour le patrimoine urbain de Giovannoni relève d’une reconnaissance du déjà là qui fonde des modalités de prises en charge de l’existant. Celles-ci posent les bases d’un renouvellement de la manière de penser l’urbanisme. La notion giovannonienne de patrimoine urbain, qui réfère à l’ensemble urbain patrimonial, devient l’élément de base d’une analyse morphologique urbanistique qui permet de conceptualiser l’agglomération contemporaine comme ensemble marqué par les ruptures et les discontinuités. Prenant appui sur une démarche dialogique, l’approche giovannonienne relève d’une mise en tension des singularités et d’une appréhension conjointe des différentes registres, ceux des formes et des forces, de l’existant et du souhaité, du penser et du faire. Giovannoni dépasse ainsi l’opposition entre continuité et rupture portée par les pratiques afin de penser l’articulation du nouveau à l’ancien. La confrontation de l’approche giovannonienne aux différentes perspectives qui ont marqué l’urbanisme moderne, montre que ces modalités de prise en charge de l’existant sont conditionnelles à l’accomplissement des promesses de la considération du patrimoine urbain. Autrement, l’association de la conservation du patrimoine urbain et de l’urbanisme culmine dans une double assimilation : l’assimilation du patrimoine urbain au monument historique d’architecture conduit à confondre projet d’urbanisme et projet de conservation.

La perception naïve non native des voyelles nasales du portugais

Les adultes peuvent éprouver des difficultés à discriminer des phonèmes d’une langue seconde (L2) qui ne servent pas à distinguer des items lexicaux dans leur langue maternelle (L1). Le Feature Model (FM) de Brown (1998) propose que les adultes peuvent réussir à créer des nouvelles catégories de sons seulement si celles-ci peuvent être construites à partir de traits distinctifs existant dans la L1 des auditeurs. Cette hypothèse a été testée sur plusieurs contrastes consonantiques dans différentes langues; cependant, il semble que les traits qui s’appliquent sur les voyelles n’aient jamais été examinés dans cette perspective et encore moins les traits qui opèrent à la fois dans les systèmes vocalique et consonantique et qui peuvent avoir un statut distinctif ou non-distinctif. Le principal objectif de la présente étude était de tester la validité du FM concernant le contraste vocalique oral-nasal du portugais brésilien (PB). La perception naïve du contraste /i/-/ĩ/ par des locuteurs du français, de l’anglais, de l’espagnol caribéen et de l’espagnol conservateur a été examinée, étant donné que ces quatre langues diffèrent en ce qui a trait au statut de la nasalité. De plus, la perception du contraste non-naïf /e/-/ẽ/ a été inclus afin de comparer les performances dans la perception naïve et non-naïve. Les résultats obtenus pour la discrimination naïve de /i/-/ĩ/ a permis de tirer les conclusions suivantes pour la première exposition à un contraste non natif : (1) le trait [nasal] qui opère de façon distinctive dans la grammaire d’une certaine L1 peut être redéployé au sein du système vocalique, (2) le trait [nasal] qui opère de façon distinctive dans la grammaire d’une certaine L1 ne peut pas être redéployé à travers les systèmes (consonne à voyelle) et (3) le trait [nasal] qui opère de façon non-distinctive dans la grammaire d’une certaine L1 peut être ou ne pas être redéployé au statut distinctif. En dernier lieu, la discrimination non-naïve de /e/-/ẽ/ a été réussie par tous les groupes, suggérant que les trois types de redéploiement s’avèrent possibles avec plus d’expérience dans la L2.

La debilidad del Estado como factor explicativo de los conflictos armados en África subsahariana en el período de la pos Guerra Fría

La presente disertación aborda la correlación circular entre la debilidad estatal y el surgimiento de los actores armados que postulan autores como Robert Rotberg o William Reno, para el análisis de los conflictos armados en África Subsahariana en el período de la pos Guerra Fría. Durante este período, en esta región diferentes conflictos estallaron —entre esos Liberia, Sierra Leona, Somalia, Ruanda o Sudán— además de ser una de las partes del mundo que sufre por el elevado nivel de precariedad estatal. Este trabajo desarrolla entonces ambos aspectos de dicha correlación circular, a saber la incidencia de la debilidad estatal en el surgimiento de los grupos armados y, en segundo lugar, el fomento de la debilidad por parte de los grupos armados ¬–denominados por varios autores como señores de la Guerra–. Por último, esta disertación sugiere unas limitaciones al alcance explicativo de la relación interactiva entre la debilidad del Estado y los actores armados, para finalmente discutir el postulado planteado por algunos autores como Béatrice Hibou o Roland Marchal, que propone que la existencia de grupos armados pueden llevar al redespliegue del poder estatal en el largo plazo.

Gaze fixations predict brain activation during the voluntary regulation of picture-induced negative affect

Recent studies have identified a distributed network of brain regions thought to support cognitive reappraisal processes underlying emotion regulation in response to affective images, including parieto-temporal regions and lateral/medial regions of prefrontal cortex (PFC). A number of these commonly activated regions are also known to underlie visuospatial attention and oculomotor control, which raises the possibility that people use attentional redeployment rather than, or in addition to, reappraisal as a strategy to regulate emotion. We predicted that a significant portion of the observed variance in brain activation during emotion regulation tasks would be associated with differences in how participants visually scan the images while regulating their emotions. We recorded brain activation using fMRI and quantified patterns of gaze fixation while participants increased or decreased their affective response to a set of affective images. fMRI results replicated previous findings on emotion regulation with regulation differences reflected in regions of PFC and the amygdala. In addition, our gaze fixation data revealed that when regulating, individuals changed their gaze patterns relative to a control condition. Furthermore, this variation in gaze fixation accounted for substantial amounts of variance in brain activation. These data point to the importance of controlling for gaze fixation in studies of emotion regulation that use visual stimuli.

Velhice e Terceira Idade: tempo, espaço e subjetividade

The elders began to be highlighted in the social scene, not only by their numerical growth, but mainly for their redeployment into new social spaces and accelerating its pace of life. This article aims to analyze the specializations and the time built around the aging and trace its repercussions in the subjectivity production of the oldest. Therefore, it was taken as the object of analysis the differentiation of old age in the aging process.

Identity, Philosophy, and the Problem of Armenian History in the Sixth Century

History and Identity in the Late Antique Near East gathers together the work of distinguished historians and early career scholars with a broad range of expertise to investigate the significance of newly emerged, or recently resurrected, ethnic identities on the borders of the eastern Mediterranean world. It focuses on the "long late antiquity" from the eve of the Arab conquest of the Roman East to the formation of the Abbasid caliphate. The first half of the book offers papers on the Christian Orient on the cusp of the Islamic invasions. These papers discuss how Christians negotiated the end of Roman power, whether in the selective use of the patristic past to create confessional divisions or the emphasis of the shared philosophical legacy of the Greco-Roman world. The second half of the book considers Muslim attempts to negotiate the pasts of the conquered lands of the Near East, where the Christian histories of Hira or Egypt were used to create distinctive regional identities for Arab settlers. Like the first half, this section investigates the redeployment of a shared history, this time the historical imagination of the Qu'ran and the era of the first caliphs. All the papers in the volume bring together studies of the invention of the past across traditional divides between disciplines, placing the re-assessment of the past as a central feature of the long late antiquity. As a whole, History and Identity in the Late Antique Near East represents a distinctive contribution to recent writing on late antiquity, due to its cultural breadth, its interdisciplinary focus, and its novel definition of late antiquity itself.

The evolution and assessment of pharmaceutical care: Structure, processes, and outcomes

The evolution of pharmaceutical care is identified through a complete review of the literature published in the American Journal of Health-System Pharmacy, the sole comprehensive publication of institutional pharmacy practice. The evolution is categorized according to characteristics of structure (organizational structure, the role of the pharmacist), process (drug delivery systems, formulary management, acquiring drug products, methods to impact drug therapy decisions), and outcomes (cost of drug delivery, cost of drug acquisition and use, improved safety, improved health outcomes) recorded from the 1950s through the 1990s. While significant progress has been made in implementing basic drug distribution systems, levels of pharmacy involvement with direct patient care is still limited.^ A new practice framework suggests enhanced direct patient care involvement through increase in the efficiency and effectiveness of traditional pharmacy services. Recommendations advance internal and external organizational structure relationships that position pharmacists to fully use their unique skills and knowledge to impact drug therapy decisions and outcomes. Specific strategies facilitate expansion of the breadth and scope of each process component in order to expand the depth of integration of pharmacy and pharmaceutical care within the broad healthcare environment. Economic evaluation methods formally evaluate the impact of both operational and clinical interventions.^ Outcome measurements include specific recommendations and methods to increase efficiency of drug acquisition, emphasizing pharmacists' roles that impact physician prescribing decisions. Effectiveness measures include those that improve safety of drug distribution systems, decrease the potential of adverse drug therapy events, and demonstrate that pharmaceutical care can significantly contribute to improvement in overall health status.^ The implementation of the new framework is modeled on a case study at the M.D. Anderson Cancer Center. The implementation of several new drug distribution methods facilitated the redeployment of personnel from distributive functions to direct patient care activities with significant personnel and drug cost reduction. A cost-benefit analysis illustrates that framework process enhancements produced a benefit-to-cost ratio of 7.9. In addition, measures of effectiveness demonstrated significant levels of safety and enhanced drug therapy outcomes. ^

Theta burst stimulation improves overt visual search in spatial neglect independently of attentional load

Visual neglect is considerably exacerbated by increases in visual attentional load. These detrimental effects of attentional load are hypothesised to be dependent on an interplay between dysfunctional inter-hemispheric inhibitory dynamics and load-related modulation of activity in cortical areas such as the posterior parietal cortex (PPC). Continuous Theta Burst Stimulation (cTBS) over the contralesional PPC reduces neglect severity. It is unknown, however, whether such positive effects also operate in the presence of the detrimental effects of heightened attentional load. Here, we examined the effects of cTBS on neglect severity in overt visual search (i.e., with eye movements), as a function of high and low visual attentional load conditions. Performance was assessed on the basis of target detection rates and eye movements, in a computerised visual search task and in two paper-pencil tasks. cTBS significantly ameliorated target detection performance, independently of attentional load. These ameliorative effects were significantly larger in the high than the low load condition, thereby equating target detection across both conditions. Eye movement analyses revealed that the improvements were mediated by a redeployment of visual fixations to the contralesional visual field. These findings represent a substantive advance, because cTBS led to an unprecedented amelioration of overt search efficiency that was independent of visual attentional load.

The Cambrian “explosion”: Slow-fuse or megatonnage?

Clearly, the fossil record from the Cambrian period is an invaluable tool for deciphering animal evolution. Less clear, however, is how to integrate the paleontological information with molecular phylogeny and developmental biology data. Equally challenging is answering why the Cambrian period provided such a rich interval for the redeployment of genes that led to more complex bodyplans.

Evolutionary history of the recruitment of conserved developmental genes in association to the formation and diversification of a novel trait

The origin and modification of novel traits are important aspects of biological diversification. Studies combining concepts and approaches of developmental genetics and evolutionary biology have uncovered many examples of the recruitment, or co-option, of genes conserved across lineages for the formation of novel, lineage-restricted traits. However, little is known about the evolutionary history of the recruitment of those genes, and of the relationship between them -for example, whether the co-option involves whole or parts of existing networks, or whether it occurs by redeployment of individual genes with de novo rewiring. We use a model novel trait, color pattern elements on butterfly wings called eyespots, to explore these questions. Eyespots have greatly diversified under natural and sexual selection, and their formation involves genetic circuitries shared across insects.

Job uncertainty and personal control during downsizing: A comparison of survivors and victims

This study developed and tested a model of job uncertainty for survivors and victims of downsizing. Data were collected from three samples of employees in a public hospital, each representing three phases of the downsizing process: immediately before the announcement of the redeployment of staff, during the implementation of the downsizing, and towards the end of the official change programme. As predicted, levels of job uncertainty and personal control had a direct relationship with emotional exhaustion and job satisfaction, In addition, there was evidence to suggest that personal control mediated the relationship between job uncertainty and employee adjustment, a pattern of results that varied across each of the three phases of the change event. From the perspective of the organization's overall climate, it was found that levels of job uncertainty, personal control and job satisfaction improved and/or stabilized over the downsizing process. During the implementation phase, survivors experienced higher levels of personal control than victims, but both groups of employees reported similar levels of job uncertainty. We discuss the implications of our results for strategically managing uncertainty during and after organizational change.

Costing police custody operations

Presents a simulation study of the costing of police custody operations at a UK police force. The custody operation incorporates the arrest, booking-in, interview, detention and court appearance activities. The Activity Based Costing (ABC) approach is used as a framework to show how costs are generated by the three “drivers” of cost, activity and resource. These relate to the design efficiency of the process, the timing and mix of demand on the process and the cost of resources used to undertake the process respectively. The use of discrete-event simulation allows the incorporation of dynamic (time-dependent) and stochastic (variability) elements in the cost analysis. This enables both the amount and timing of the use of capacity and the generation of cost to be established. The concept of committed and flexible resources directs management decisions to the redeployment of unused capacity or alternatively the identification of additional capacity requirements.

From icon to naturalised icon:a linguistic analysis of media representations of the BP Deepwater Horizon crisis

This research explores how news media reports construct representations of a business crisis through language. In an innovative approach to dealing with the vast pool of potentially relevant texts, media texts concerning the BP Deepwater Horizon oil spill are gathered from three different time points: immediately after the explosion in 2010, one year later in 2011 and again in 2012. The three sets of 'BP texts' are investigated using discourse analysis and semi-quantitative methods within a semiotic framework that gives an account of language at the semiotic levels of sign, code, mythical meaning and ideology. The research finds in the texts three discourses of representation concerning the crisis that show a movement from the ostensibly representational to the symbolic and conventional: a discourse of 'objective factuality', a discourse of 'positioning' and a discourse of 'redeployment'. This progression can be shown to have useful parallels with Peirce's sign classes of Icon, Index and Symbol, with their implied movement from a clear motivation by the Object (in this case the disaster events), to an arbitrary, socially-agreed connection. However, the naturalisation of signs, whereby ideologies are encoded in ways of speaking and writing that present them as 'taken for granted' is at its most complete when it is least discernible. The findings suggest that media coverage is likely to move on from symbolic representation to a new kind of iconicity, through a fourth discourse of 'naturalisation'. Here the representation turns back towards ostensible factuality or iconicity, to become the 'naturalised icon'. This work adds to the study of media representation a heuristic for understanding how the meaning-making of a news story progresses. It offers a detailed account of what the stages of this progression 'look like' linguistically, and suggests scope for future research into both language characteristics of phases and different news-reported phenomena.
